    Quality of life
    Opis:
    Parkinson’s disease can lead to disability and reduce the quality of life of its patients. The purpose of this study is to evaluate the quality of life of a group of people with Parkinson’s disease. The clinical and progressive characteristics of the disease, its motor and neuropsychological impact were evaluated in each Parkinsonian subject included in the study. A quality of life assessment was performed and collected from 60 Parkinsonian patients followed and hospitalized at Hassan II University Hospital in Fez. Different instruments were used, the Hoenh and Yahr scale and the Parkinson’s disease questionnaire (PDQ-39) UPDRS engine, MMS, clinical fact sheet. According to our results, through the different tests and scale of evaluation, we observed an impaired quality of life in the areas of physical discomfort, cognitive disorder, activity of daily living, mobility, and emotional well-being, especially in patients with duration of evolution more than 5 years. There was no significant difference between the two sexes. In addition, the severity of the disease tended to give the impression of an impaired quality of life with respect to the dimensions of activities of daily living and cognition, which is relevant to improving the quality of life patient life and clinical interventions.

    Opis:
    Academics have been curious about what motivates pro-environmental behaviour. However, a few research studies have been conducted to analyse and comprehend the pro-environmental behaviour of those in charge of service and production (employees). The COVID-19 outbreak highlighted this topic, emphasising the significance of employees’ pro-environmental behaviours (PEBs) in promoting and maintaining business sustainability. Therefore, this study contributes to the body of knowledge by investigating employees’ PEBs during the COVID-19 pandemic. In-person and online surveys were used to reach the staff of hotels and travel agencies in Egypt’s most popular tourist areas. The quantitative data were analysed with SPSS 25. The results revealed that employees of the tourism and hospitality industry are exceptionally engaged in PEBs in times of the COVID-19 pandemic. Also, the findings indicate that the structure of tourism and hospitality employees’ PEB comprises six factors: operation activities, habits, organisation rules, health, energy-saving, and environment-related activities. However, their behaviour must be guided and improved in three key areas (personal health, organisational rules, and operation activities). According to this study, employees may follow certain practices without understanding their justification or significance. In practice, the study presents recommendations that might increase the industry’s resistance to challenges in improving the pro-environmental behaviour of industry employees.

    Opis:
    This paper presents a baseband model and an enhanced implementation of the wireless full duplex analog method introduced by [1].Unlike usual methods based on hardware and software self- interference cancelation, the proposed design relies on FSK modulation. The principle is when the transmitter of a local end is sending data by modulating the carrier with the appropriate frequency deviation, its own receiver is checking if the remote transmitter is using the opposite deviation. Instead of architectures often used by both non-coherent and coherent receivers that require one filter (matched filter for coherent detection) for each frequency deviation, our design uses one mixer and one single integrator-decimator filter. We test our design using Universal Software Radio Peripheral as radio frequency front end and computer that implements the signal processing methods under free and open source software. We validate our solution experimentally and we show that in-band full duplex is feasible and synthesizable for wireless communications.

    Opis:
    Burn-out or exhaustion syndrome is caused by a prolonged exposure to a chronic professional stress. Public Health Professionals are the most exposed to this kind of risk. The ultimate goal here is to determine the prevalence of the burn-out and search for factors associated with this pathology among those who work in the field of health. Our sample, which is from the Ibn Sina Hospital in Rabat, consists of 150 nurses, 80 doctors, and 40 administrators. A self-questionnaire was employed, the Maslach Burnout Inventory (MBI) as well as a clinical interview. The results of this study show a high degree of burnout. Moreover, 56.66% of participants show a high level of emotional exhaustion, 45.18% suffer from a high level of depression. Meanwhile, the loss of a sense of personal accomplishment is high among 48.51% of those surveyed. The emotional exhaustion observed among people who have worked for a long time ago is associated with the means of transportation used and to the unsuitable hours of work. Depersonalization exists among elderly people and the oldest at work. This study confirms the existence of a high level of burnout among health professionals. Many socio-demographic and socio-professional factors contribute to the increase in the level that people are affected. These factors encourage the promotion of better working life conditions.

    This study aimed examine the impact of Ascorbic acid spraying once and twice at concentrations 250 and 500 mg/L on the concentration of some nutrients in the seeds of the bean plant (Vicia faba L.) grown on soils contaminated with nickel at concentrations 30 and 60 and lead at concentrations 300, 600 mg/kg soil.The results showed that soil treated with 600 mg/kg lead has a significant decrease of concentration of magnesium, phosphorous, potassium and chloride in the seeds of the bean plants which amounted to 1.16 , 1.121, 4.113 and 0.071 mg/g, respectively compared to the control group. It was also found that spraying the vegetative parts of the bean plant with 250 mg/L ascorbic acid twice was attributed to increasing of magnesium significantly in the seeds of the bean plant, which amounted to 4.00 mg/g. otherwise, spraying with the same concentration, but once, led to a significant increase in phosphorous concentration, which reached 1.335 mg/g. The results also showed that one-time spraying of 500 mg/L ascorbic acid led to a significant increase in chloride concentration, which amounted to 0.395 mg/g compared to the control group. The results show that lead treatment had a more negative effect on the concentration of nutrients compared to the effect of nickel. It was found that spraying with ascorbic acid at a concentration of 250 mg/L was significantly superior to the concentration of 500 mg/L of magnesium, phosphorous, potassium and chloride in the seeds of bean plants. Also, spraying with ascorbic acid once was superior to spraying twice with the concentration of both magnesium and chloride.

    Opis:
    One of the most dangerous field problems in the civil engineering discipline is the suddenly developed cracks in the building, which could be caused by the swelling of the subsurface soil. Thus, this work has focused on employing a procedure in the geographic information system known as the inverse distance weighted (IDW) technique, to analyze the extent of cracks in a residential complex in the city of Kirkuk in Iraq using the physical and chemical soil data for seven boreholes from the field of the study. Physical soil parameters such as liquid limit (LL), gravel, sand, silt and clay percentages were characterized first, followed by chemical properties such as gypsum content (GYP), total suspended solids (TSS), potential of hydrogen (pH), and organic content (ORG). Furthermore, statistical studies such as plasticity index (PI) and soil characteristics association, linear single, and various linear multi-regression models were used. The data analysis shows that there are significantly positive and negative relationships between PI as a swelling indicator and the physical and chemical soil properties, although weak to moderate correlations were observed between PI and these variables. The PI values were accurately predicted by the proposed linear multi-regression models of the physical and integrated physical and chemical soil characteristics, with multiple R values of 0.92 for both models. As a result, the suggested statistical models can provide complete geographic and mechanical explanations for the crack sources in the investigated residential complex.

    This paper details a hardware implementation of a distributed Ɵ(1) time algorithm allows to select dynamically the master device in ad-hoc or cluster-based networks in a constant time regardless the number of devices in the same cluster. The algorithm allows each device to automatically detect its own status; master or slave; based on identifier without adding extra overheads or exchanging packets that slow down the network. We propose a baseband design that implements algorithm functions and we detail the hardware implementation using Matlab/Simulink and Ettus B210 USRP. Tests held in laboratory prove that algorithm works as expected.

    Opis:
    In Jordan, the unprecedented proliferation of building projects is anticipated to increase the potable water demand in the construction manufacturing. In the present work, secondary treated wastewater (STW) and potable water (PW) were used in the production of concrete mixes, which were subjected to testing after 3 to 28 days of curing to determine how the, mechanical properties of concrete was affected by the addition of secondary treated wastewater in various proportions (25-100%). Results indicated that the use of 25% and 75% of secondary treated wastewater in concrete production increased the compressive strength to 39 MPa after 28 days of curing. A more noticeable increment was recorded in tensile strength, which was double that achieved with the standard design. Overall, the compressive strength increased by 21.95% when secondary treated wastewater was used, while the expenditure related to water usage was halved. Furthermore, there was consistency between the results obtained from scaling up to actual ready-mix concrete production and the results of the empirical work.

    Unilateral Spatial Negligence
    Parkinson's Disease
    Bell's test
    Opis:
    In Africa, few studies are interested in unilateral spatial neglect (NSU) in Parkinson's disease. However, this syndrome is a deficit to detect, respond to or orientate towards meaningful stimuli (Heil- man, KM 1973), observable after an injury affecting the non-dominant hemisphere for language. The significant handicap it entails justifies the need for early diagnosis and care. The NSU study is mo- tivated by its link with neurocognitive phenomena that are important on the theoretical level (attention, visuospatial and perceptual awareness). The objective is to study USN in Parkinson's pa tients, followed and hospitalized at the Neurology Department of Hassan II University Hospital in Fez. The visual-graphic test that has been used to detect this pathology is that of Bell's test. The test focuses on the detection of targets placed among several stimuli on a sheet of A4 paper. The material included 120 people: 60 Parkinsonian patients: 34 men (56,7%), and 26 women (43,3%) and 60 control subjects: 34 men (56,7%), and 26 women (43,3%). The groups were matched by age and sex. Different aspects of neglect have been observed throughout the Bell's test. It was found that total omission of bell figures was significantly influenced by age, being less frequent in the 35-49 age group in both groups, and higher in the elderly (50-80 years), as well the level of education. It have been reduced considerably with the increase in education. The hand used and the laterality had no effect; t = 3.76 degrees of freedom (df) = 108.27 and p = 0.000. Unilateral spatial neglect has a negative effect in subjects with Parkin- son's disease. It deserves to be systematically sought for a better clinical evaluation and therapeutic management of the patients.

    Opis:
    The primary purpose of the current study is to investigate the entrepreneurial self-efficacy as an antecedent to persistency among entrepreneurs. In addition to that, the study examines the mediating role of entrepreneurial passion between entrepreneurial self-efficacy and entrepreneurial persistence. Lastly, the study explored the relationship between financial literacy and persistence and its moderating role between entrepreneurial passion and persistence. Structural equation modeling through of partial least square bootstrapping resampling was used for hypotheses testing to analyze the data collected from a sample of 273 Malaysian entrepreneurs. The results of the study supported all arguments broached in the current research for the subjective norm, entrepreneurial self-efficacy, which showed a significant impact on entrepreneurial passion and entrepreneurial persistence. The moderating effect of financial literacy on entrepreneurial passion and entrepreneurial persistency was also highly significant. The current work is among the pioneering studies that examine entrepreneurial self-efficacy, entrepreneurial passion, financial literacy and entrepreneurial persistence among entrepreneurs.
    Głównym celem niniejszego badania jest zbadanie własnej skuteczności przedsiębiorczej jako czynnika poprzedzającego wytrwałość wśród przedsiębiorców. Ponadto badanie bada mediacyjną rolę pasji przedsiębiorczej między samowystarczalnością przedsiębiorczą a wytrwałością przedsiębiorczą. Wreszcie w badaniu zbadano związek między znajomością finansów a wytrwałością oraz jej moderującą rolą między pasją przedsiębiorczości a wytrwałością. Do testowania hipotez wykorzystano modelowanie równań strukturalnych za pomocą częściowego ponownego próbkowania ładowania metodą najmniejszych kwadratów, aby przeanalizować dane zebrane z próby 273 malezyjskich przedsiębiorców. Wyniki badania potwierdziły wszystkie argumenty poruszone w bieżących badaniach na rzecz subiektywnej normy, własnej skuteczności przedsiębiorczej, która wykazała znaczący wpływ na pasję przedsiębiorczą i trwałość przedsiębiorczą. Bardzo istotny był również moderujący wpływ wiedzy finansowej na pasję przedsiębiorczości i trwałość przedsiębiorcy. Obecna praca należy do pionierskich badań, w których analizuje się skuteczność przedsiębiorczą, pasję przedsiębiorczą, znajomość finansów i wytrwałość przedsiębiorczą wśród przedsiębiorców.

    Opis:
    It is an established fact that when roads are planned and constructed, consideration needs to be given to ensuring the strength of the road surface. It is, however, also the case that when an existing road is being rebuilt or is under maintenance, its base may need to be fortified to increase the road’s vehicle-carrying capacity. The base may, for example, contain a high proportion of weak soil that would be difficult, time-consuming, and costly to remove. This paper aims to investigate the efficacy of using sand-filled piles to reduce road deformation. Experiments conducted on sponge samples confirm that there is a relationship between the total area of sand-filled piles and relative reduction in deformation. It finds that the relationship is non-linear, but that the relationship can be made linear by adjusting the area of sand-filled piles. When the area of sand-filled piles increases from 7.8% to 19.4%, the deformation module can change by up to 100%. Relative reduction in deformation can change from 14% to 45.5% when the area of sand-filled piles increases from 7.8% to 11.7%. The maximum reduction in deformation - 92.4% - occurs when the area of sand-filled piles exceeds 19.5%. Changing the loads borne also affects the deformation module. This paper found that when there was a 10 to 15kg load, and the number of sandfilled piles was increased, there was a change in the deformation module by 380-470%. When there was only a 5kg load on the sample, and the number of sand-filled piles was increased, there was a change in the deformation module by up to 1217%.

    Opis:
    According to United Nations reports, natural disasters caused, worldwide, approximately 100,000 deaths and affected 175 million people each year between 2004 and 2013. To reduce those numbers, countries around the globe have made specific arrangements enabling them to warn the population about imminent disasters, in order to evacuate the area in due time. But providing such warnings in areas where no Internet access is available poses a great challenge. In this paper, we proposed a method to transmit early warning messages via UMTS cellular networks, while relying on spare extensions of control channels (FACH). The results obtained are validate based on their comparison with theoretical considerations and are also benchmarked against the 3GPP standard. The results show that messages may be sent faster than with the use of the 3GPP standard.
